I refinished the wood floors in a small bedroom by sanding with 150 grit paper, using a random orbital sander. Applied the first coat fairly thickly. Looked very nice, though a few little bald patches remained. I figured that was fine, since I was going to use 3 coats.
I waited 5 hours, then applied second coat. But, humidity was kinda high, the floor was very slightly tacky underfoot. I wore socks(!), and I probably didn't use enough poly on the fleece roller pad.
Result: In one patch in particular, right by the door, I've now got a very marred surface: Hairs, sock fibers, streaks (from me trying to remove the hairs with a mineral spirit-soaked paper towel!), bubbles, nastiness all round.
My plan is to wait 24 hours, sand the area with 150 grit again, just to smooth things out a bit, then apply a thicker coat, and hope everything smoothes out. Any suggestions, please? My reputation's on the line: The wife had confidence in me...now she's not so sure!

having many countless hours of experience with poly and wood, i would recommend that you go ahead and resand the floor with something a bit rougher. say 100-120 grit to remove some of the bubbles and hairs etc.
once you get that done, wash the floor thoroughly to get the dust and stuff up. working from a corner, use a roller to apply poly in 1 square yard sections. after rolling, use a brush to smooth the surface and remove any bubbles. (very important tip). do not apply very thick layers, you will get a better result with 3 thin layers. also, give the floor time to dry, read the instructions on the container for recommended application drying times.
as i mentioned in the subject line, these types of projects take time and patience. you will never get a completely perfect hair/dust/lint free surface, due to the nature of gravity,lol. but if you sand it wash it , do small sections and nap it with a brush, you will get good results. the last floor i did, the customer wanted a high gloss. you shoulda seen the looks in their eyes when they returned from vacation, lmao.
good luck.

150 is too much for a wood floor to accept a finish. Has to do with surface tension.
The smoother it is, it has a tendency to bead the finish as you apply. Like a waxed car in the rain, so to speak.
Thinner coats are better then thick coats. Thick coats are brittle. and don't dry right.
Sand with 100 and use a thin coat of finish.
